Want to install an aftermarket coolant temp sensor but don't want to cut into your radiator hose? Me either! Instead of doing that simply unbolt your factory coolant neck and install this spacer in between the neck and the head.
The spacer has the provision for a 1/8 NPT provision or alternatively if used in conjunction with a barbed fitting this spacer could be used as the source for a coolant breather tank.

- Direct bolt on
We can only confirm fitment for the vehicles listed above under vehicle compatibility. If your car is not listed there, then we don't know if it will fit.
Do you make these to suit other cars?
We only sell the parts listed on our website. If it's not listed on our website, then we don't sell it. Sorry.
What's the advantage of using the GKTech coolant neck spacer?
Typically to gain a coolant temperature reading you would need to cut the OEM radiator hose. In this case, our plate sandwiches up against the head so it is much safer than a cut in between a flexible hose which is then sealed with clamps. This is also a good spot to use for a swirl pot setup or additional bleeder line.
What modifications are required, is this hard to fit?
No modifications are required, simply just remove and refit.
Is there anything else needed for installation?
We do recommend a small amount of sealant on either side to avoid a coolant leak. In terms of the spacer it will arrive as shown in the product photo.
Can I install this myself? If so how long will installation take?
Yes, it is straightforward. Install time should be around 15 minutes, you will also need to bleed your cooling system after this has been fitted.
NOTE: These will NOT fit front wheel drive SR20's.
S13 SR20 180SX
S13 SR20 SILVIA
